4 Claims. (Cl. 30-12) This invention relates to safety razors and hasfor the primary object the provision of a device of the above statedcharacter which includes a novel construction of blade and holdertherefor whereby the blade is removable from the holder and so connectedto the handle of the holder that it will readily adjust itself to theguard when the latter carried by the handle is brought into engagementwith the blade so as to assure proper l0 functioning of the device whenin use.

" With these and other objects in View this invention consists incertain novel features of construction, combination and arrangement ofparts to be hereinafter more fully described and l5, claimed.

For a complete understanding of our invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1 isa perspective view illustrating a safety razor constructed in accordancewith our invention.

Figure 2 is a side elevation illustrating the same.

Figure 3 is a detail sectional view illustrating 2i the connectionbetween the handle and blade.

' Figure 4 is a detail sectional view illustrating the guard adjusted tothe blade.

Figure 5 is a plan view illustrating a modified form of leg.

Figure 6 is a sectional view illustrating a modified form of holderadaptable to the type of blade shown in Figure 5.

Referring in detail to the drawing, the numeral l indicates a bladehaving a cutting edge 2 and a thickened backing 3 provided with a cutoutportion intermediate the ends of the blade for the purpose of receivinga block 4. Opposite walls of the cutout portion of the blade areprovided with projections 5 adapted to snap into recesses 6 formed inopposite walls of the block for the purpose of detachably connecting theblade to the block. The block 4 is of hollow formation so that therecessed walls thereof are capable of flexation to permit the lugs 5 tosnap in and out of said recesses. An opening is formed in one end vofthe block to receive one end of a shank '7 and said end is pivotallyconnected to opposite walls of the block by a pin 8. The pivot betweenthe shank and the pivot between the blade and the block permit saidblade to have a limited universal movement with respect to the shank.The shank forms an integral part of a handle 9 and the shank is ofrectangular shape in cross section and has formed upon the oppositewalls thereof ribs 10 provided with offset ends 11. A sleeve 12 isslidable on the shank and carries a guard 13. The guard is in the formof a plate 14 having one edge laterally offset to form a guard flange 15adapted for association with the cutting edge of the blade 1. The plate14 is offset where it forms onto the sleeve 12 to form a pocket 16 of asize to receive a portion of the block 4 for retaining the block againstpivotal movement on the shank. Opposite walls of the sleeve 12 areprovided with grooves 17 shaped correspondingly to the ribs l0 so thaton adjustment of the guard to the blade the grooves receive the ribs 10and retain the block in the pocket and the guard adjusted properly toone of the side faces of the blade. The plate 13 of the guard has formedthereon retaining flanges 18 adapted to overlie the noncutting edge orthickened portion of the blade when the guard is adjusted to the bladefor the purpose of preventing the blade from pivoting with respect tothe block 4. Projections 19 are formed on the plate 14 of the guard tocontact with one face of the blade for properly positioning the cuttingedge with respect to the guard flange 15.

As shown in Figure 5, the blade 20 is of a thin or wafer type having acutting edge 20' and the opposite edge thereof cut away toreceive acasing-like element 21. The element 21 Aconsists of a wall 22 andflanges 23 offset to form channels adapted to receive opposite walls ofthe cutout portion of the blade 20. The flanges 23 are provided withprojections 24 adapted to snap into sockets formed on a block 25. Theblock 25 is pivoted to the shank of the handle. The guard 26 issimilarly constructed to the guard 13 except that the pocket is omittediA safety razor constructed in accordance with the foregoing descriptionand as shown in the drawing will permit the blade to be easily andquickly removed or applied and when applied to be readily adjusted tothe guard or the'latter adjusted to the blade so as to assure properfunctioning of the razor while in use.

While we have shown and described the preferred embodiment of ourinvention, it will be understood that minor changes in construction,combination, and arrangement of parts may be made without departing fromthe spirit and scope of our invention, as claimed.

Having described the invention, we claim:

1. A safety razor comprising a blade, an element pivotally anddetachably connected to the non-cutting edge of the blade, a handlepivoted to saidelement, and a guard for the said blade and slidablymounted on the handle to engage 251 f j j;-

a handle pivoted to the block, a guard 'slidably mounted on the handleand having a pocketvto receive the block to prevent pivotal movement ofthe block with respect to the handle 'and to hold to the block byengaging said blade, and means for retaining the guard in said position.

4. A safety razor comprising a blade, a block pivotally and detachablyconnected to the blade, a handle pivoted to the block, a guard slidablymounted on the handle and having a pocket to receive the block toprevent pivotal movement of the block with` respect to the vhandle andto hold the blade-against pivotal movement with respect to the block byengaging said blade, ribs on the handle, and a sleeve on the guard toengage the ribs.
